9. This isn't entirely accurate

Zimmerman waived the stand your ground defense. His trial was just straight and simple self-defense. Had Zimmerman argued stand your ground, he would have lost.

Alexander lost her stand her ground defense when she retreated and was no longer in danger. She left the scene by going out of the house. At this point, she removed herself from danger. She then grabbed a gun, and then re-entered, and fired two shots. One of those shots deflected in such a way that it thankfully missed her kid in the next room. Had that bullet not deflected, it would have killed the kid. Under the law, the fact that she retreated and re-entered, makes her the "aggressor."
Alexander would have the right to stand her ground had her husband chased her and then she turned around and shot him. That would be self-defense. The husband stayed in the house. Her correct move should have been to call the police.

Even if you had never passed stand your ground, Zimmerman would still be not guilty and Alexander would still be in prison. The problem is Florida's draconian minimum sentencing laws (which were pushed hard by Jeb Bush and Charlie Crist). These laws prevent judges from looking at the situation. Yes, Alexander was being abused by her husband. Had the law allowed flexibility, the judge certainly would have made this a light sentence. But these laws don't allow judges any leeway anymore. The judge had no choice.
